Extraction cleaning with plenum and air outlets facilitating air flow drying

摘要

A portable cleaning apparatus includes a base module having a base housing with a bottom base wall, and enclosing a fan. The base module is moveable along an external surface in a first direction. The fan can move air through the base housing from an interior of the base housing to exteriorly of the base housing through an exhaust outlet in the base housing. A plenum fluidly communicates at a first end with the exhaust outlet and at a second end with at least one plenum outlet opening. The at least one plenum outlet opening is between the base wall and the external surface. The at least one plenum outlet opening can direct air exhausted from the interior of the base housing along the external surface in a second direction perpendicular to the first direction.
